Specification of Letters Patent.

Patented July 11, 19111.

Application filed september 15, 1909. Serial No. 517,764.

Improvements in Qzonizers, the following] being a full, clear, and exact disclosure of the oneform ofmy invention which I at present cleempreferable.

For a detailed description of the present form of my invention, reference may be had to the following specifieationand-to the accompanying drawings forming a part thereof, in which Figure l is a plan; Fig. 2 is a central lon-.

gitudinal section; Fig.3 is an end elevation inside the casing.

The main purpose of my invention is to eliminate an important part of the insulation heretofore required in ozonizers and provide for grounding one side of the high tension circuit and also ground'ingthe cool-- ing apparatus.

It 'also includes certain features hereinafter described and claimed.

Referring to the drawings, A is the external casing, B is a box of thin metal connected to the grounded side of thecircuit. On each of the longer sides of box B and on 'the inside thereof are a series of vertical metallic bars E, E, etc., which constitute the discharge points of the electrode. The bars E are perforated at intervals in a direction parallel to the longer sideof the box, and through these perforations extend a series of metallic pipes forming a cooling coil J such as is shown the section of the central electrode appearing in Fig. 2 for receiving a gasified liquid, or in some cases cold water, or brine. Since the said box B is grounded,

the pipe coil need not be insulated as here tofore. Against the faces of the discharge bars E is placed a thin sheet of glass or micanite D which is separated a slight distanee from a parallel sheet of like material resting against the faces of similar discharge bars on the outside of the central electrode.

Between these sheets passes the gas to be ozonized.

The central electrode consists of an internal metallic box G, having as aforesaid, the vertical discharge bars E, E, etc., on its outer sides. This box is insulated from thesurrounding box by blocks 9, 9, etc.', and is connected to one side of the circuit-by a wire H, passing through an insulating tube'lz in the top side of box B. Within the central metallic box G is a cooling coil P, like the coils J. It is however, insulated by oil or other liquid insulator from the box G in which it is contained, being supported in the box by insulating blocks 7c, 70, etc, and where it passes through the top side of the box, the outgoing end is enlarged to receive within it the incoming end, and thereby call for only one insulatingbushing S, i The coil P will be connected to the coils J and to ground, so that the only insulation required in my apparatus is that forthecentral elece trode. It will furthermore be observed that the oil layer between box G and the grounded pipe coil P creates a condenser shunting eachdischarge gap between the central electrode and the outer one. Hence at each impulse of alternating current there will follow a series of oscillating discharges from the condenser, and also that this condenser is formed by the interior construction of the apparatus itself and is, moreover, cooled by the same means which cools the other parts. This will add materially to the output of the machine. This also involves an exact equalization of the discharge capacity of the gaps on opposite sides, which are connected in multiple to the transformer or other source of electrical energy. The term grounded is used herein, in its comprehensive sense.

What I claim as new and desire to secure by Letters Patent is:

i 1. An ozonizer containing a central insulated electrode, a grounded electrode on each side thereof and a grounded cooling device inside of and insulated from the central" having a series ofdischarge surfaces there.

on spaced at intervals and an insulating sheet resting against said discharge surfaces and forming one side of the space-containing the gas to be ozonized.

6. An ozonizer containing two electrodes each having a series of discharge surfaces spaced thereon and oppositely disposed and insulating sheets resting against the respective discharge surfaces and forming a space between them for the gas to be ozonized.

7; An ozonizer electrode forming one plate of a condenser shunting the discharge gap between said electrode and an opposite electrode.

8. A cooling device for an ozonizer electrode forming with the electrode a condenser shunting the discharge gap between-said electrode and an opposite electrode,

9. An ozonizer electrode forming also a plate of a condenser shunting the discharge p one, and a cooling device for said condenser.

10; An ozonizer containingtwo discharge Copies of this patent may be obtained for between said electrode and the oppositegaps in multiplel the said gaps having sub-' stantially equal ischarging capacity, and a shuntingcondenser.

11. An ozo'nlzer having two electrodes, a

condenser within the ozonizer shunting the-- discharge gap between said electrodes and a cooling device for said condenser.

12. An ozonizer comprlsing a grounded metal tank, the opposite walls of which constitute electrodes, a second metal tank inside. of and insulated from said grounded tank andhaving oppositely disposed walls -constituting electrodes, and a grounded cooling device in said inner tank surrounded by a non-conducting liquid.
